If you want more software and don't want to go looking for software repos. Just go into YaST and you'll see an option called "Package Search(Webpin)" It will search Packman and you can install packages without subscribing to the repo.

You'll most likely be able to get the MP3 enabled xine there, DVD playback, VLC and codecs.

Go to YaST>Software Repositories, Click Add and put just what's in this image.

You might have to do the nomodeset thing like in my thread. A reboot shouldn't be needed usually because the Nouveau driver was never in the kernel up until recently, now it is, it needs to be disabled because it conflicts with the binary driver as said.

I don't understand the router issue, since it's not in the equation. If your wireless card is live and connected to your network, then that's it. Are you talking about connecting to it via the web browser?

I must admit, I'm not the ideal person to talk to in regard to networking and router setup.
